Jade necklace with Greek Goat God Pan, from thrift store auction

Hello, I was studying this and noticed a few things. The Goat God use to be a brooch and they took off the clip and poured more metal on the back side of it, it is not magnetic. So at one time the beads were without the Greek God. I also think the clasp (fish) is from a different place than the pendant, This makes sense as the beads are probably from Asia. I admit I do not understand Jade but again if I like something and it is a good price, I buy it! These beads are large and the necklace is maybe 30+ inches. I put in bank box and did not measure it. Thank you for looking. Don
